VULNERABILITY DETAILS:

CVE ID: CVE-2012-3304 (PM54356)

DESCRIPTION: WebSphere Application Server could allow a remote attacker to hijack a valid user’s session, caused by an error in the Administrative Console. An attacker could exploit this vulnerability to gain privileges of the victim.

· Mitigation(s): When you have the Administrator Console open, do not use your web browser to visit other websites. Open another web browser to visit other websites.

CVE ID: CVE-2012-3311 (PM61388)

DESCRIPTION: WebSphere Application Server, when running on z/OS could allow a local attacker to bypass security restrictions, caused by a failure to perform CBIND checks when using Federated Repositories for IIOP connections using Optimized Local Adapters. An attacker could exploit this vulnerability via a client application to access or modify application data.

DESCRIPTION: WebSphere Application Server could allow a remote attacker to traverse directories on the system. An attacker could exploit this vulnerability by deploying a specially-crafted application file to overwrite files outside of the application deployment directory.

DESCRIPTION: IBM HTTP Server may be vulnerable to a denial of service. By sending a specially-crafted Secure Sockets Layer (SSL) packets to the vulnerable Web server, a remote attacker could cause a segmentation fault.

DESCRIPTION: WebSphere Application Server could allow a cross-site scripting attack, caused by improper validation of input by the help system in the Administrative Console. A remote attacker could exploit this vulnerability using a specially-crafted URL to inject script in a victim's Web browser within the security context of the hosting Web site. CVSS:

AFFECTED PLATFORMS: The following IBM WebSphere Application Server for distributed operating systems, IBM i operating systems, and z/OS operating system Versions are affected: · Version 8.5 Liberty Profile only

REMEDIATION: The recommended solution is to apply the Fix Pack or PTF for each named product as soon as practical

Fix:

Apply a Fix Pack or PTF containing this APAR PM67082, as noted below:

For IBM WebSphere Application Server :

For V8.5: o Install Fix Pack 1 (8.5.0.1), or later.

· Workaround(s): None

· Mitigation(s): none

CVE ID: CVE-2012-4851 (PM68643)

DESCRIPTION: WebSphere Application Server V8.5 Liberty Profile could allow a cross-site scripting attack, caused by improper validation of the URI. A remote attacker could exploit this vulnerability using a specially-crafted URL to inject script in a victim's Web browser withing the security context of the hosting Web site. CVSS:

CVE ID: CVE-2012-3325 (PM71296)

DESCRIPTION: If you have installed an Interim Fix for PM44303, or a fix pack containing PM44303, you have the potential for an authenticated attacker to bypass security restrictions, caused by an error when validating user credentials. This could allow a user to gain unauthorized administrative access to an application and potentially gain access to confidential and critical customer data.

DESCRIPTION: WebSphere Application Server and WebSphere Virtual Enterprise are vulnerable to a denial of service, caused by an error in the proxy server component. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to cause the proxy to be marked as down and deny access to applications.
